Two years ago Roanoke City Parks and Recreation wanted to get people off their couch with the Roanoke 100 miler program. It begins again tomorrow. 850 participants signed up in the first year, and 1,200 did last year. Those who sign up at roanoke100miler.com are pledging to walk, run, bike, paddle or exercise 100 miles or more between January 7th and April 15th. WFIR’s Gene Marrano has the story.
